IMPROVEMENT IN GRAIN-BINDERS.

I Specification forming part of Letters Patent No. 195,098, datedSeptember 11, 1877.; application filed April 16, 1877. 7

To all whom it may concern:

Be it known that I, HENRY CURTIS, of Chicago, in the county of Cook andState of Illinois, have invented a new and useful Improvement inGrain-Binders, which improvement is fully set forth in the followingspecification, reference being had to the accompanying drawings, inwhich Figure l is a rear elevation of a portion of a grain-harvester towhich my improvement is attached, showing the various parts in twopositions. Fig. 2 shows a plan of the same. Fig. 3 shows a thirdposition of the bindingarm B, 8210., mainly showing the compressor dafter having been acted upon by the finger. f. Figs. 4 and 5 showmodifications, which will be hereinafter explained.

The object of my invention is to give to the binding-arm of agrain-binder a suitable motion by means of a driving-crank and a sinuous binder-arm carrier, provided with a longitudinal cam-shaped slot,which slides upon a fixed stud or pin; also, to operate thegraincompressor by means of a finger or lug projecting from a point nearthe end of the driving-crank.

I am aware that a binder-arm has been hitherto mounted directly onadriving-crank, and that binder-arms so mounted have been guided bypassing their straight rear ends through a fixed guide, by'pivoting themto a swinging link or sway-bar, and by arranging their rear ends toslide in fixed slotted guides, as in the application of John H. Gordon,filed July 1, 1876, and such arrangements I do not claim, my machinebeing designed as an improvement upon, and being subordinate to, thesaid Gordon invention.

In the drawings, A is a frame-work surrounding the driving-wheel W, thehorizontal timbers A of which support the binding mechanism, and thegrain as it is out is carried by elevators, as indicated by the arrowsw, and delivered to the binder.

D is a skeleton standard resting upon an adjustable platform, E, andsupporting the binding-arm B and other parts. The shaft a rests in abearing at the upper part of the standard D, and has keyed to it thecrank O and sprocket-wheel G, all of which are rotated by the chains b.

The binding-arm carrier F is pivoted to the pin 10 of the crank, and asit is carried around by the said crank the slot 0 glides along the studg, which is fixed rigidly in the standard D. i

The binder-arm bar P, Fig. 2, is fastened to the carrier F at a pointnear the pin of the crank, and extends horizontally some dis-- tancetherefrom, when it bends at a right angle toward the grain-receptacle,and is properly tapered and curved to the form of a binding-arm, B.

The slot 0 in the carrier F is given such a shape that a properdirection is given to the motion of the point of the binding-arm as itis operated by the crank C.

It will be observed that the slotted arm, the form or curve of which maybe varied indefinitely, admits of the binder-arm being given any motionrequired, renders the machine simple and strong, and avoids thenecessity of extending the supporting frame or standard backward to theextent required in machines using the stationary slotted guides.

The fixed pin h passes through a slot, 70, in the connecting-bar H, andgives to the sliding plate L an intermittent reciprocal motion, by meansof which a suitable wire-twisting device beneath the platform E isoperated.

The twisting head or device may be either stationary or movable, and ofeither of the common and well-known forms in general use, the presentinvention having no relation thereto.

The compressing-rod d is journaled in the carrier F and arm B, and atone end is bent and curved to form a suitable grain -compressor,-d,while at the other it is provided with a pointed lug, t, and attachedguard 0, Figs. 1 and 3. The spiral spring 8, Fig. 2, tends to keep thecompressor 01 swung back from the binding-arm, and to keep the guard 0against the head of the crank O.

The crank O is provided with a projecting finger, f, which, as the crankrevolves, presses the lug i, and forces the compressor (1 toward thebinding-arm, to compress the gavel, as shown in Fig. 3, said compressorbeing allowed to swing back by the exertion of the spring 8 as therevolution of the crank is continued.

The bindingmechanism is designed to be mounted so as to be adjustablebodily forward or backward.

It may be desirable to provide the pin 9 with a friction-roller, asshown at n in Fig. 5, or to employ a dovetail groove, e, Fig. 4, in theside of the carrier F, instead of the slot above described.

I claim as my invention 1. In a grain-binding machine, the combi-.nation of a sinuously-slott'ed binder-arm carrier, a fixed stud havingsaid carrier mounted and arranged to slide thereon, and a rotatingdrivin g-crank connected directly with the carrier, substantially asshown and described.

2. The crank 0, provided with afinger, f, in.

combination with the compressing-rod d, provided with the lug 'i andguard 0, substantially as shown and described.

3. In a grain-binding machine, a drivingcrank provided with a finger, f,a binder-arm carrier mounted on and carried by said crank, and acompressing-rod, 11, arranged and operated by means of the finger,substantially as shown and described.

4. The combination of the slotted binderarm carrier F, mounted on thecrank G, and fixed stud g, with the stud h, bar H, binderarm, and bar P,substantially as shown.

5. The combination of the binder-arm and slotted carrier-F, mounted onthefixed stud g, and crank G, with the stud h, bar H, and movabletwister-operating device L, substantially as shown.

6. 1311- a grain-binder, the combination of a binder-arm and a sinuousor bent carrier attaohed'thereto, a rotary driving-crank con nected toand, bearin g said carrier, and afixed stud or guide, g, having thecarrier arranged to slide and pivot thereon as it is moved by the crank,so that as the carrier is moved by the crank it receives by the actionof the guide a sinuous or irregular movement, substantially as shown anddescribed.
